DESCRIPTION

Boat bumpers

Object of the invention

The present invention relates to a bumper or bumper for boats preferably from work boats in ports, floating structures, patrol boats, firefighters, tugs ... and all types of work vehicles and industrial transport, SUVs, etc.

More specifically, the present invention relates to a bumper provided with at least one frustoconical body for the mechanical damping of direct impacts or collisions caused by external elements on said bumper and thus obtaining protection of the hull of the boat or bumper of the ship.

Background of the invention

In the state of the art longitudinal pieces are known cut in isolation and that can be screwed to the hull of the ship in the areas or surfaces of the ship most susceptible to direct impacts to collisions.

For example, techniques relating to bumpers in the form of "D" which are disclosed in the utility models CN205311858, CN206579809 and CN206050006 may be cited. In these utility models, techniques related to boat bumpers comprising a tubular body made of elastic material such as rubber or elastic plastic and in which semi-circular or "D" shaped elongated damping structures are integrally formed, such that the protection of the ship's hull along the surface of the bumper is achieved.

In particular, CN205311858 describes a "D" shaped bumper for boats that allows adhesion to the ship's hull by means of a super adhesive and waterproof film.

CN206579809 describes a "D" shaped rubber bumper for boats comprising a semicircular minor base that functions as a bumper and a second guide-shaped surface designed to fit the surface of the ship.

Additionally, the second guide-shaped surface comprises a plurality of holes that allow optimum installation of the bumper in the hull of the ship.

This type of linear parts may not usually have an optimum impact absorption in the case of collisions with other vessels or other ships or with solid surfaces such as docks or grip platforms because the force generated by the impact is not distributed homogeneously along its surface. Another disadvantage offered by this type of bumper of modular "D" shaped parts is that they do not adapt easily to the shape of the ship's hull and can present an irregular final finish, with imperfect joints and terminations that can affect the exterior appearance of the ship.

For this reason a bumper is necessary for ships that, having dimensions as arbitrary as possible, improve the disadvantages of the prior art in relation to the absorption of impacts; making it more effective and homogeneous and distributed along the surface of the bumper, and that the use of said bumper achieves a more aesthetic end result that avoids irregular finishes and / or imperfect terminations that may affect and / or hinder the upper base of the bumper. ship. Additionally, the desired bumper should allow easy installation at any point on the surface of the ship.

Description of the invention

The bumper for boats of the present invention solves the problems of the state of the art mentioned above and achieves the aforementioned advantages, since it comprises:

A truncated conical body of variable thickness comprising a smaller base adapted to dampen impacts caused by elements external to the bumper and an open larger base adapted to come into contact with the ship. Said bumper is characterized in that the minor base comprises an inverted truncated conical drawing that reaches the major base. Said inverted truncated conical central drawing is fixed to the ship by at least one mechanical fastener.

Furthermore, the damping of the minor base causes the retraction of said minor base with respect to the open major base such that the minor base never protrudes outside the dimensions of the open major base.

Thus, the bumper of the present invention can absorb impacts in at least a first phase of mechanical damping due to deformation of the first frustoconical body and allows a homogeneous distribution of the loads by impacts thanks to the variation of the thickness of the first frustoconical body, deforming first the areas of the smallest thickness and finally the thickest.

Additionally, the bumper according to the present invention allows easy installation on the ship by means of the use of the fastening element for fixing said inverted truncated conical central drawing. In other embodiments, the bumper of the invention may comprise up to a deformation damping phase and a second pneumatic damping phase that increase the functionality and effectiveness thereof.

Said bumper can be installed in different areas of the ship's surface. Preferably, the bumper of the invention is designed for boats but could also be used in the machine. In other embodiments, the bumper of the invention can be used in pleasure boats, SUVs, cranes, etc. In other embodiments, the bumper of the invention can be used in workboats in ports, floating structures, patrol boats, firefighters, tugs ...

The bumper of the present invention can be easily adapted to the surface of the ship thanks to the fixing of the inverted truncated conical central drawing by means of the mechanical fastening element that simplifies the installation of said bumper. Some examples of mechanical fasteners may be a screw, rivet, etc.

The dimensions of the bumper of the present invention may comprise curvilinear (for example, circular) or straight (for example rectangular, square, triangular) shapes, depending on the design of the ship and the type of ship.

To increase the protection of the hull of the ship, the bumpers of the present invention can be distributed in line, in parallel, in tresbolillo or in any desired combination.

In some examples, the bumper of the present invention may comprise two truncated conical bodies where the first frustoconical body offers a first phase of deformation damping and where the second inverted truncated conical body with respect to the first frustoconical body offers a second damping phase pneumatics. The second truncated conical body also allows a homogeneous distribution of the loads by impacts thanks to the variation of the thickness of the second truncated conical body, first deforming the areas of smaller thickness and finally those of greater thickness. The surfaces of said truncated conical bodies can be smooth inside and out or have undulations to facilitate the deformations stepwise.

Preferred Embodiment of the Invention

As seen in the figures, and according to a preferred embodiment according to the present invention, the bumper for boats as shown in Figure 1A comprises a frustoconical body (1) of varying thickness with a smaller base (2) adapted for cushion impacts caused by elements outside the bumper and an open base base (10) in contact with the ship. The frustoconical body (1) is flexed in the resting position to adapt the entire length of the open base (10) to the hull of the boat or bumper of the boat and increase the bumper fixation. The elements external to the bumper can be, for example, other ships, artificial structures such as docks, platforms, walls, or natural structures such as rocks, mountainous walls, etc.

The bumper is characterized in that the minor base (2) comprises an inverted central truncated conical drawing (11) that reaches the major base (10). The inverted central truncated conical drawing (11) can be fixed to the ship by at least one mechanical fastener (3). The damping of the minor base (2) causes the retraction of said minor body (2) with respect to the open major base (10) such that the minor base (2) never exceeds the dimensions of the open major base (10) .

In this embodiment, the whole truncated cone body is formed by an elastic material with damping properties such as rubber.

Figure 1B shows the frustoconical body (1) of variable thickness and the smaller base (2) of said body that dampens impacts by mechanical damping as well as the mechanical fastening element (3) and the inverted central truncated conical drawing (11) that reaches the main base (10) open.

Another embodiment of the bumper of the present invention can be seen in Figure 2A where the minor base (2) which is adapted to dampen impacts caused by elements external to the bumper comprises a high hardness protection element (4) installed by adhesion and which can be be formed by the same material that forms the frustoconical body but of superior hardness. It can also be seen in Figure 2A the truncated cone body (1), the mechanical clamping element (3) and the open main base (10) that can come into contact with a surface of the ship (not shown in the figure). The frustoconical body 1 is flexed in the rest position to adapt to the entire hull of the open base (10) to the hull of the boat or bumper of the boat and increase the bumper fixation. Some examples of elements clamping mechanics can be a thyme, rivet, etc.

Figure 2B shows the high hardness protection element (4) installed by adhesion for this particular embodiment. Other ways of installing the high hardness protection element (4) can be carried out in other embodiments, such as by sealing, welding, etc. Figure 2B also shows in its cut view the frustoconical body (1) with the minor base (2) adapted to dampen impacts caused by elements external to the bumper, as well as the mechanical fastening element (3) that fixes the inverted central truncated conical drawing (11) to the ship.

Another embodiment of the bumper of the present invention can be seen in Figure 3A where the minor base (2) adapted to dampen impacts caused by elements external to the bumper comprises another high hardness protection element (5) external to the minor base (2) of the frustoconical body (1) and which is installed by screwing (6). The frustoconical body 1 is flexed in the rest position to adapt to the entire hull of the open base (10) to the hull of the boat or bumper of the boat and increase the bumper fixation. The number of screws comprising the screwing (6) can be evenly distributed along the surface of the high hardness protection element (5) which is screwed to the smaller base (2) as can be seen in Figure 3B. Additionally, in said figure 3B, the frustoconical body (1) can be seen with the minor base (2) adapted to absorb impacts by mechanical damping and the open main base (10) in contact with the ship, as well as the mechanical fastening element ( 3) and that fixes the inverted central truncated conical drawing (11).

Another embodiment of the present invention can be seen in Figure 4A. In this embodiment, the boat bumper comprises the frustoconical body (1) with the smaller base (2) adapted to dampen impacts caused by elements external to the bumper and a larger open base (10) in contact with the ship. Additionally, it can be seen in said figure that the bumper for boats comprises a second inverted truncated conical body (7) with respect to the first truncated conical body (1) of varying thickness as well as the first truncated conical body (1) and housed inside the frustoconical body (1). Additionally, the truncated conical body 1 is flexed in the rest position to adapt in its entire perimeter of the open base (10) to the hull of the boat or bumper of the ship and increase the bumper fixation.

The second truncated cone body (7) comprises a major base (8) adapted to dampen impacts caused by elements external to the bumper by pneumatic damping and an open bottom base (12) in contact with the ship. Like the first frustoconical body (1), the second frustoconical body (7) allows a homogeneous distribution of the loads by impacts thanks to the variation of the thickness of the second frustoconical body (7), first deforming the areas of smaller thickness and finally the thickest.

It can be seen in Figure 4A, that the open bottom base (12) is fixed concentrically inverted central truncated conical drawing (11). Thus, the bumper of Figure 4 comprises two damping phases that increase its functionality and effectiveness. A hole (9) for draining air resulting from pneumatic damping can also be seen in Figure 4A.

A bottom perspective view of the bumper of Figure 4A can be seen in Figure 4B. Figure 4B shows the frustoconical body (1) with the smaller base (2) adapted to dampen impacts caused by elements external to the bumper, the open main base (10) as well as the fixing element (3). In addition, the second inverted truncated conical body (7) can be seen with respect to the truncated conical body (1) and which is also housed within the truncated conical leather (1). Thus, this embodiment can absorb the impacts in a first phase with mechanical damping of the frustoconical body (1) and in a second phase by pneumatic damping of the second inverted truncated conical body (7). It can also be seen in Figure 4B that the major base (8) comprises an adjustable orifice 9 for emptying the second inverted truncated conical body (7).
